Elsewhere, Asus has made a few other evolutionary improvements. Like the Prime, the Infinity has a rear 8-megapixel camera, but now the camera has a slightly wider aperture for low-light shooting--f2.2 instead of the Prime's f2.4. Asus updated the camera software, too, as well as the sensor and flash; but in my casual shooting the benefits of these enhancements were minor in low-light and daylight shooting. In side-by-side comparisons, I preferred the images captured by the Infinity; the color and clarity was simply better than the Prime. (Another note: The high-res display made it easier to capture images, too.) The front-facing camera has been updated from 1.2 megapixels to 2 megapixels, so you can now obtain high-definition video chat.
The Infinity also bumps up the Bluetooth support to Bluetooth 3.0. Ports remain the same as on the Prime: a Micro-HDMI output, a MicroSD card reader, and a proprietary connector to use with the charger/USB transfer cable or the optional keyboard dock. Like the other models in Asus's Transformer line, the Infinity morphs into a clamshell-style netbook when you snap the tablet into its $150 Mobile Dock; it uses the same dock as the Prime.
Asus retains some of its now-standard Android customization features, including a custom keyboard that includes white keys with black text and a number row, and a control panel for quick access to the tablet's power settings, display controls, Wi-Fi and Bluetooth toggles, rotation lock, and other settings.
Preloaded apps include Polaris Office, SuperNote, App Backup, App Locker, Asus Sync, MyNet (for streaming 1080p content across a network), and Asus Webstorage (with 8GB of free storage space for the "lifetime" of the unit, up from the Prime's one-year of free unlimited storage followed by paid storage).
As with the Retina-display Apple iPad, your experience with how apps look will vary. Apps that have been optimized for the high-resolution display can look great, while those that lack higher-resolution assets may be a pixelated mess. Case in point: Riptide GP looks great on the Prime but looks garbled and outdated on the Infinity. Other apps, including Amazon's Kindle app, looked good.
Sadly, I did encounter some odd behavior while transferring media to the Infinity from my Windows 7 PC. For example, I got error messages on the PC that the device was in use when I queued up more than one folder transfer; that alone is not entirely unusual among tablets, but then I received follow up error messages that aborted the copy. I also had several apps, including the browser and the camera, close unexpectedly; hopeful these glitches are ones that Asus will clean up with its first over-the-air update.
